System error sends multiple newsletters for users

I’m registering a disaster that happened to my newsletters. Due to an error with MailPoet, each of my subscribers received more than 15 emails in a single day, resulting in a massive cancellation on our user base.

The sad thing is that this is the second time that this happened (we’ve had the same issue last year).

I’ve contacted MailPoet’s premium support, but it’s taken son long for them to act, that the system fired 15 extra newsletters per user, again.

I’m really devastated by the amount of subscribers that I’ll loose for this, so let this be a warning for all interested in testing this plugin.

I can’t imagine a single site feeling happy with an automatic procedure that sends multiple newsletters at once to its subscribers.

There is not excuse for this, ok? If you suspend and reactivate a newsletter, please don’t send old emails. You cannot assume that newsletters are atemporal, or worse, don’t recognize that no one wants to be over-flooded by newsletters at once.

I’ve had more than 40 formal complaints and more than 300 cancellations because of it.
